"r0 ALL WHOM IT MAY CONCERN:

' I Be it known that I, ALBERT W. ROBERTS, of Hartford, county of Hartford, and State of Connecticut, have invented certain new and usefulimprovcments inthe process or the employmentof Mechanism for Drying Leather, Staple, or other material; and to enable others skilled in the art to make and use the same I will proceed to describe'the process or mechanism by which it is produced by referring to the drawings, in which the same letters indicate like parts in each of the figures. v

The nature of this invention consists in combining mechanism for receiving-and forcing air with air-receiving, circulating, and heating tubes, arrunged vithin a' heated chamber, (as a chamberpf-a steam boiler or other heater, which is-constructed expressly for heating or generating steam, &c.,) with a proper receptacle or room for placing hides, leather, staple, or other material, for being dried.

The objectof this invention is to use accumulated artificial heat, used for heating, generating steam, 81-0.,

"for heating air for drying, without any expense for fuel. In the accompanyingdrawings- Figure 1 is a front elevation. Figure 2 is a side elevation. Figure 3 isa top orplan view.

The boiler and walls,its front, and fire heating apartment are very much like those now in commonuse. A are air-heating tubes, arra'nged 'in the fire-chamber B of a. boiler or other heated chamber,-(usecl for purposes other than fordrying,) so that the heat ofthe fire may pass or mingle and circulate among the tubes, and so that the surfiwes-thereof may. be heated without essentially detracting the heat from the boiler, or other purpose for which it was originally provided. 0 is a ihn-blowcror its equivalent, such asare in .common use, which eounects'witli the induction pipe D. This blower is operated by'means of a belt working upon the pulley E in the drdinariwaiy. The speed of. this blower (air-pump) or -itsequival ent,. for blast and heat, may be increased or diminished, more or less, according to the'amountor change of. heat required, according to the warying circumstanees'ofthe case. F is an eductio n pipe, which conducts the airintothedrying apal-tmcnt'G through the tubes A. This apartment G is provideclwith grates, rachs, shelves,&c., for'the convenience of-hanging or placing the article in proper position for drying, and is made of any desirable size or shape which will be best adapted for thepurpose for which it is used. This apartment G is also provided with openings for the escape or displacembnt of air when desirable also to, regulate the condition of.- the air within the apartment. Now, it will be clearly seen that, when the power is applied to the pulley E of the air-pump or blower, or their-"equivalents, the air will be drawn into the bl0wer,and forced forward therefrom, through the heating tubes and eduction tube, into the drying-aparti'nent G, which may beheated to a greater or less degree by the velocity or pressure of the blower O or its equivalent. 7 r

I believe I have thus shownthe nature, construction, and mode or process of operation so as to enable others skilled to make and-use the same therefrom. I What I claim, therefore, and desire to secure by Letters Patent, is a Driving the air through heating tubes A, arranged-in a heating chamber, B, into a drying apartment,"G,. substantially as and for the purpose describe i i i A.
